Glock 22 Kb at the range today

[Breakdaddy]

I was at the range firing my XDs and PM9 today and the guy next to me was firing his .40 Glock 22. About halfway through a mag he had a Kb which I took some snaps of on my cell phone. He was using winchester white box ammunition, so I dunno what happened. Didnt appear to be a squib. Pulled the barrel and it looked fine. Weird. Another guy next to us said he'd never heard of a glock malfunctioning like that. I have heard of it from here and other boards, but never witnessed it myself.

 

[W.E.G.]

I'd bet he had previously fired lead-bullet ammo.

Makes a ring in the chamber, and can prevent other ammo from going into full battery.

Wouldn't that also cause some degree of a bulge in the barrel as well though?

And it's very strange, if it was a barrel obstruction, that the frame lost a big chunk of plastic where it did. My vote would be for some type of instability in the polymer (and perhaps other parts as well) rather than anything else.

Definitely weird..

Never seen a G22 KB do that kind of Damage...

Thier arent many on record and most were due to User mistakes.
Non-Jacketed Ammo, Hot Handloads/Reloads, Improper/lack of Maintenance, Squibs, Early barrels with little if any support.

+1 Imperfection in or Improperly Molded Polymer would do it.

It looks like a typical KB -- firing out of battery with a consequential failure of the unsupported case wall, venting downward in this case, into the frame and blowing it out.

It may well have been lead buildup from earlier shooting with handloads.

 

[W.E.G.]

No.

The bullet went right down the barrel the way it is supposed to.

The lead build-up (if in fact that was the issue) would not act as obstruction such that would cause the barrel to bulge.

Its just as possible that this was a damaged WWB round - either damaged right out of the box, or damaged by the operator.

The thing we can be pretty sure of, is this was an out-of-battery discharge.

What exactly caused it, I'm sure we will never know.

 

[NGIB]

OK have to do it.

C'Mon Glockers, tell us this isn't possible and that these are just doctored photos. Just goes to show than all mechanical instruments can and do fail and that nothing is "perfection".

OK, sarcasm off, hate to see anything like this happen to anyone...

 

[W.E.G.]

At least the Glock has the decency to explode properly when an OOBD happens. The metal frame pistols just bend (sometimes "just a little") and leave the owner not sure if its safe to keep firing or not.

 

[brigadier]

That REALLY looks like a flaw in the molding. Not a KB, just part of the frame body popping out. From what I have read, Glock is very good about taking care of things like this, so he should just send it in for a complete replacement.

I'd love to see a photo of the blown out brass and the firing pin indentation.

Goes a long way to figuring out what happened.

I'm betting fired out of battery. Biggest design/manufacturing flaw in Glocks. Guns are not supposed to fire unless locked up fully -- big advantage to external hammer designs, if the slide is not fully closed, it interferes with the hammer fall.

+1

If the cartridge case is not fully inside the chamber and barrel when detonation occurs, you get this type of failure. It's the only way it can happen and still leave the barrel intact.

Maybe on the Old versions, not so much on the newer ones.

 

[hexidismal]

Every time I've ever seen documented evidence of a glock KB (and there has been a bunch of them) it's ALWAYS been a gun chambered in .40S&W. I've heard tales of others, but the confirmed ones were all 40s.

wally Me too. Could be bad brass or over pressure round.

NOT the gun's fault

I would be willing to bet he was not using factory jacketed ammunition like every Glock owner's manual says to do.

And to answer the .40 cal having KB's I think you are 100% correct. 40 S&W is a hot round and when they are loaded up even hotter Glock can definitely have problems. I have seen the entire top action blown off due to some idiot running fast burning powder handloads. It does make for good reading (maybe people will start reading the owner's manual and following it). Hope no one was hurt.

 

[DENALI]

All I can say is this is an awfully mild KB if thats what it is. I've seen two of them in my life so far and they were far more destructive than this one(shattered frames)both with minor injury to the shooter. Hope you guy's saved all the ammo in question. Good luck...................

The G22 slide looks like a 2-2.5 Gen, by the looks of the old extractor; but it has a 3rd Gen frame/reciever.

I can't really read the serial number; certain Glocks had a recall, if my memory serves me correctly.

I hope the shooter's hand is OK.

I agree and it looks like the old finish on the slide too. I’ll bet it was one with the frame that got recalled, but this shouldn’t have anything to do with the KB. The barrel probably is one of the older ones with less case support.
